WEIBER Forced Convection Ovens use a motor driven circulating fan that is placed between the unit’s inner and outer housings. A timer is placed inside them that control the fan and the heating element. This kind of ovens work faster than conventional ovens because it uses the fan that keeps on circulating to ensure that even distribution of heat and faster cooking takes place.

Forced convection ovens are basically designed to save time of heating. The temperature that is inside these units are moderated through hydraulic type thermostat or with a digital controller microprocessor based temperature controller cum indicator to achieve maximum accuracy.

These are also known as heat advection. There are many types of mixing that can also utilize forced convection to basically distribute one substance to another. Forced convection can even happen by natural means such as when the heat of a fire causes expansion of air and bulk air flow. In this type of process the fan rapidly circulates hot air forces heat faster than would naturally happen due to simple heating even without a fan.

In a Forced-Air Oven (electric convection), a fan circulates hot air rapidly through the oven’s interior. This rapid, forced circulation insures temperatures throughout the oven are uniform and heat is transferred more evenly. By blowing hot air past the product, it prevents cooler air from building up near product surfaces you are trying to dry. Since products in a convection oven are always in contact with hot air, products pick up heat faster and dry faster.

Forced Convection Oven

  1. WEIBER laboratory forced convection ovens are double walled convection heated and cooled units. Outer body of lab ovens are constructed out of thick PCRC, pre coated corrosion resistant GI sheet duly pre-treated with primers and rust proofing and painted with long lasting stove enamel or elegantly powder coated. The inner construction is made of heavy gauge stainless steel sheet of SS-304 grade). The gap between the walls is filled high grade mineral glass wool, which ensures maximum thermal efficiency in our ovens.
  2. Heating:
  3. Indirect heating system is provided in our units, comprising of air heaters made of high grade Kanthal/Nichrome wires of suitable wattage. The warm air is evenly distributed throughout the oven through efficient motor fans ensuring very good temperature sensitivity.

  4. Temperature control:
  5. The temperature inside our forced convection ovens is controlled through Nano technology based ergonomic controller (HMI & PLC controller).

  6. Temperature Range: Temperature range of our standard oven is 250o C.
  7. Air circulation:Triple walled back of unit is fitted with circulation fans for maintaining temperature uniformly throughout the ovens.
  8. Features of Coaxial Circulation Fan:

    • Vacuum impregnated stator winding with dr. back varnish under red baktol
    • Non-hygroscopic.
    • Best IR value
    • Bright bar (EN - 8 class) shaft.
    • Bush bearing of branded companies.
    • Surge comparison testing in fans and pumps eliminates into turn short circulating of the stator.
    • Pressure die-casted-rotor manufactured with zero error.
    • Boats of high accuracy
